Check out this phenomenal TED-Ed Human Body YouTube playlist from Richard Byrne:
SO many options for use in the Health classroom. How about something as simple as using the question feature in Google Classroom and asking the students to view one of the videos and then add 2 things they learned from watching.
The cool thing about the question feature is that the students cannot see other responses until AFTER they respond.
To extend the lesson, require students to reply to another student's response, expanding on what that student mentioned. This offers great opportunity to discuss appropriate interactions online.
